Lal'c, full name "Lal'c Melk Mark", is an important character in Top o Nerae! 2: Diebuster. She is the pilot of Buster Machine 19, "Dix-Neuf" and the holder of the highest kill score among the Topless. Nono admires her and refers to her as "Onée-sama" (お姉様), most likely a reference to Noriko's calling Kazumi by that name in Gunbuster.
